What's the harm of not eating meat?
Although a lot of fat comes from meat, in addition to fat, meat also contains many vitamins and minerals that the human body needs, which is to coordinate the nutritional balance in the body and help the body run, which many vegetarian dishes do not have.
In addition, meat contains animal protein needed by human body to provide nutrition for muscles. If you don't eat meat, your muscles will gradually lose nutrition. The consequence of losing muscles is that your body's daily metabolic rate will decrease.
If you refuse to eat meat, it means malnutrition. In the long run, it will lead to decreased immunity, poor skin, loose body and low metabolism, and become a "fat-prone" constitution.
